Sen. Cassidy knocked out of Louisiana Republican primary as Trump-backed Letlow, Fleming make runoff

U.S. Rep. Julia Letlow has advanced to a runoff in Louisiana’s Republican Senate primary. State Treasurer John Fleming came in second to join her in the next round of voting. Letlow capitalized on the power of President Donald Trump’s endorsement in another attempt to purge his party of people he views as disloyal. Trump supported Letlow over incumbent Sen. Bill Cassidy, one of the few Republican senators who voted to convict him during his second impeachment trial over the attack on the U.S. Capitol on Jan. 6, 2021. Cassidy has also clashed with Health Secretary Robert F. Kennedy Jr. . By receiving less than 50% of the vote, Letlow and Fleming were unable to avoid a runoff. It takes place June 27.
